Our first special filament based on the Amphora 3D polymer. Reinforced with 20% specially sourced carbon fibers, this filament is perfect for parts which need high stiffness. XT-CF20 has a beautiful matte surface finish when printed.
CARBON FIBER IS ABRASIVE:
A special point of attention is the abrasive nature of the carbon fibers. In general these fibers will accelerate the nozzle-wear of brass nozzles, much faster than unfilled filaments. Therefore we recommend to use hardened steel nozzles.

colorFabb XT-CF20 is a copolyester based carbon fiber composite material that is based on the unique Amphora 3D polymer from Eastman Chemical and is loaded with no less than 20% specially sourced carbon fibers suitable for 3D Printing.
Combining carbon fibers in filaments material is not a new idea, but colorFabb has been able to combine a lot of desired properties into 1 new material :
- Extreme High Flex Modulus (6.2 GPa), twice as stiff as PLA/PHA
- Moderate strain at break (8-10%), so no extreme brittle filament, but toughness
- High Glass Temp. (Tg = 80C)
- Very high Melt strength
- Very high Melt Viscosity
- Good dimensional accuracy and stability
- Low odor / Styrene Free solution
- Easy processing on many platforms
- High attractive matt black surface
CARBON FIBER IS ABRASIVE
A special point of attention is the abrasive nature of the carbon fibers. In general these fibers will accelerate the nozzle-wear of brass nozzles, much faster than unfilled filaments. There colorFabb recommends to use nozzle’s from Stainless steel or hardened copper alloys.
Just think of all the great applications for a variety industries, that now will have a material that performs according to expectations. Functionality, stiffness, dimensional stability, heat resistant, what more can you ask? Applications in the RC Industry / Drones / Aerospace / Automotive / Prototyping and many more can now be developed on your desktop 3D Printer.
AMPHORA 3D POLYMER
ColorFabb XT-CF20 is produced wih AMPHORA 3D Polymer from Eastman Chemical.
Amphora 3D Polymers is a specially developed co-polyester just for 3D Printing. It’s toughness and high meltstrength makes it the perfect material for producing fiber reinforced composites, providing the necessary viscosity for 3D printing, combined with a high toughness in the filament and end application
- Good and beautiful - but maybe not much more
However, what I found was that for stiffness I was much better off with standard grade PLA, maybe even annealed PLA, while this material for me formed a rather weird, soft-ish texture that would bend more than expected, and that with thicker walls.
I was printing with 0.4mm nozzle, 260°C, and speeds around 40mm/s
Another thing to look out for are the "Nozzle blobs". This material will stick to the nozzle and create blobs of itself that grow in size until they get stuck to the print and ruin it. I have no idea why or how, but it makes printing with this over longer times more of a gamble.
However, once thing this material does is look good, and has GREAT temperature and overhang stability while and after printing, as well as appropriate layer bonding!
So at least one thing is somewhat good. (Posted on 11/12/2016)
- Excellent... when you get it right!
- great but with challances
The only problem I find is that sometimes with the material a big chuck comes out (something I do not have with any other material) and as this material is super fast very hard and strong, this chuck can be in the way and destroy a print.
On my sigma with a springloaded bed, this usually is not much of a big problem, but on my kossel XL with no spring loaded bed a huge issue and the collision between the chuck and nozzel will force the printer to be out of alignment and ruing the print.

- I Love This Stuff
And naturally, I was a bit skeptical when I ordered my first roll of XT-CF20, but I was (and continue to be) amazed by this product. I use this filament mostly for fabricating or enhancing RC aircraft parts, including landing gear struts.
Before I found XT-CF20, I would have never even considered using a 3D printed part for something like landing gear struts that can take some serious abuse, especially during hard landings. But I have been able to use XT-CF20 for things like this with confidence. In fact, I have found that I am more likely to damage my airframe than break a part printed with XT-CF20.
It's true that you do have to work a bit to get your 3D print job parameters set right for this filament, but once you do, the parts are not only strong but look great too.
So far, this is the most useful, most durable 3D printer filament that I have found, and before I found this filament, I didn't think it was possible to make 3D printed parts that would rival commercial grade OEM parts in terms of strength and durability, but I am convinced that parts printed with XT-CF20 actually do.
I love this filament and always make sure to order more before I run out so that I can be certain to always have some on hand.

- Approuved by Copterlab
We reviewed lot of 3d printed carbon filament and finally this is the best we used (for the moment) ;-)
Nozzle temp: 260°c
Bed temp: 50°c
Buy with confidence. (Posted on 11/7/2015)
- This is some sexy-smexy stuff
The only question that remains for me is, what took you so long, Colorfabb? ;) (Posted on 9/8/2015)
- Bin enttäuscht
Jedoch ist das drucken mit dem CF20 ein Qual. . Jede neue Geometrische Form benötigt ihre eigene sehr sensible Einstellung. 3 Rollen Bestellt. Und nach 5 Tagen dauertest gebe ich auf... Die paar Ergebnisse die nach vielen hin und her gespiele in den Einstellungen erwecken nicht den Eindruck eines Prozesssicheren Materials. Sehr schade.

- Fantastic product
All colorFabb 3d printing filaments are produced in our own production facility, situated in the Netherlands. Since no external parties are involved in the making of colorFabb filament we can ensure consistent quality on every order.
Excellent diameter tolerance
An important machine in our production are the laser measurement systems used to check the diameter of our filament real time during production. It’s measured over 1000 times per second and helps us guarantee that each spool of colorFabb 3d printing filament produced within tolerance. We can guarantee 0,05mm +/- on both 2,85mm and 1,75mm colorFabb 3d printing filament, which means you can rest assured that your printer is extruding the exact amount of material.
Within minutes of production a spool of colorFabb 3d printing filament is sealed airtight with a double barrier foil. To go the extra mile, we’ll also seal the fancy cardboard box that we use to ship our product. You can make sure colorFabb 3d printing filament is fresh and ready for 3d printing when you’re done unboxing.
The colorFabb testlab features a wide range of popular 3d printers. We’re continuously testing on our 3d printers to keep checking the quality of the materials we produce and to develop exciting new materials for the maker community. If your not sure how to print with our materials on your 3d printer, please contact us at firstname.lastname@example.org
The following printers are used in our lab:
- Ultimaker Original
- Ultimaker Original Dual Extrusion
- Ultimaker 2
- Makerbot Replicator 2s
- Delta Tower (E3D hot-end)

ColorFabb was founded as a brand of Helian Polymers, a sister company of Peter Holland which have been active in the master batch and additives for the plastics processing industry. Our knowhow, network and partnerships is driving material innovations and quality. You can expect colorFabb to keep on developing interesting new materials, which will be tested on a variety of printers to make sure it’ll get the job done.
At colorFabb we have a well equipped 3d printing studio with a lot of popular 3d printers. We know our materials will give you excellent results and to help you get these results here are tips and trick for using colorFabb 3d printing filament.
Adviced 3d printing temperature:
Adviced 3d print speed:
40 - 70 mm/s
Advised Heated bed
For colorFabb_XT we advice to print on a heated bed. After printing, the build plate needs to cool down to about 20-30 C at which point you can remove the printed part.
Since colorFabb develops and produces their own filaments we have a lot of knowhow about our materials. Here you’ll find all kinds of interesting material specifications that will help you decide which material is best for your project.
